BACKGROUND Technical Field

Exemplary embodiment(s) of the present disclosure relate to rampdeployment systems and, more particularly, to an automated cargo vehicleramp deployment system for configured to selectively displace a rampalong a perimeter of a cargo vehicle during loading and unloadingoperating conditions.

Prior Art

It used to be, if you were moving yourself or needed storage, you hadabout two options. Option one, rent a vehicle, pick it up, load it up,drive it to the storage unit you rented, unload it, drive back to thevehicle rental place, drive home. And when it was time to pick yourstuff up again, well, you know the drill, just in reverse. Option twowas, pay through the nose for the luxury of someone to bring a storageunit to you and hope it's delivered when you need it, have it sit therefor a while—good luck with that if you live in an apartment—then hopeit's picked up when you need it gone.

Furthermore, different cargo vehicles have loading/unloading doorspositioned on different sides of the perimeter of the cargo vehicle.This makes it difficult to use a conventional ramp stored at a rear sideof the cargo vehicle. For example, a traditional ramp can weigh between150-200 lbs. With seven different configurations, the doors can bepositioned anywhere on all three sides of the cargo vehicle; on eitherlongitudinal side and the end. Many configurations have multiple doorswhich will require repositioning the ramp several times. Then dependingon the circumstances, the ramp may need to be as short as seven feet andas long as fourteen feet.

Accordingly, a need remains for an automated cargo vehicle rampdeployment system in order to overcome at least one of the above-notedshortcomings. The exemplary embodiment(s) satisfy such a need by anautomated cargo vehicle ramp deployment system that is convenient andeasy to use, durable in design, versatile in its applications, anddesigned for configured to selectively displace a ramp along a perimeterof a cargo vehicle during loading and unloading operating conditions.

Advantageously, the associated cable 39 includes a firstassociated cable 39 a and a second associated cable 39 b incommunication therewith and configured in a substantially figure-eightpattern for pulling the car 36 in opposed directions along the guiderail 35 while prohibiting the first associated cable 39 a and the secondassociated cable 39 b from being undesirably tangled.

In a non-limiting exemplary embodiment, the guide rail 35 is extendedalong at least one side of the cargo vehicle 12.

In a non-limiting exemplary embodiment, the guide rail 35 is extendedalong at least two sides of the cargo vehicle 12.

In a non-limiting exemplary embodiment, the guide rail 35 is extendedalong at least three sides of the cargo vehicle 12.

In a non-limiting exemplary embodiment, the second automated rampdisplacement mechanism 22 further includes an articulation mechanism(e.g., actuator, hydraulic or pneumatic piston, etc.) operably coupledto the car 36 and the ramp 11 for selectively articulating the ramp 11between the vertically oriented raised position and the non-verticallyoriented position defined below (e.g., declined to the ground surface) ahorizontal position relative to the vertically oriented raised position.

In a non-limiting exemplary embodiment, the ramp includes a femalesection 40 and a male section 41 slidably engaged therewith.Advantageously, the third automated ramp displacement mechanism 23including a ram operably engaged with the female section 40 and the malesection 41 and configured to selectively extend and retract thelongitudinal length of the ramp 11.

The present disclosure further includes a method of utilizing anautomated cargo vehicle ramp deployment system 10 for configured toselectively displace a ramp 11 along a perimeter of an existing cargovehicle 12 during loading and unloading operating conditions. Such amethod includes the steps of: providing a controller 13 and a powersource 14 connected thereto; providing and locating a ramp 11 at theexisting cargo vehicle 12; providing a first automated ramp displacementmechanism 21; providing a second automated ramp displacement mechanism22; providing a third automated ramp displacement mechanism 23;operatively coupling each of the first automated ramp displacementmechanism 21, the second automated ramp displacement mechanism 22, andthe third automated ramp displacement mechanism 23 to the controller 13and the power source 14; the first automated ramp displacement mechanism21 configured to selectively displace the ramp 11 from a first position24 to a second position 25 defined along a perimeter of the existingcargo vehicle 12 while the ramp is maintained at a vertically orientedposition; the second automated ramp 11 displacement mechanism 22configured to selectively displace the ramp 11 from one of the firstposition 24 and the second position 25 to a third position 26, whereinthe third position 26 is a non-vertically oriented position; and thethird automated ramp displacement mechanism 23 selectively adjusting alongitudinal length of the ramp 11 while the ramp 11 is staticallydisposed at a third position 26.

During experimentation, many configurations and ramp manufacturers wereconsidered until it was finally decided to design a proprietary ramp 11and associated displacement mechanisms 21, 22, 23. The biggest challengewas making it easy for anyone in any physical condition to both deployand stow the ramp. In particular, the system 10 stows the ramp 11 in avertical position behind the cab behind the passenger's seat but itcould also be stored behind the driver's side of the cab. The operatoris presented with a security keypad, primarily intended to make thesystem 10 child safe. Once the correct code is entered, the operator cantransition the ramp 11 in front of a cargo vehicle 12 door of his/herchoosing. There are numerous safety features incorporated into thesystem 10. For instance, once the ramp 11 is initially moved, thevehicle can no longer be started. Additionally, once the ramp 11 startsto be lowered it can no longer traverse to the next-door position. Andof course, there are warning lights and audible signals that activatewhen appropriate. All of this results in the safe and effortlessmovement of the ramp 11.

To accomplish displacement of the ramp 11 in a variety of directions, aguide rail 35 and car 36 was developed that could traverse a two-hundredpound plus ramp 11 around a perimeter of the cargo vehicle 12 (vehiclebed) including the corners. The system 10 allows the two-hundred-poundramp 11 to telescope out to about 14 feet while remaining parallel tothe ground, all of which exerts tremendous leverage against the system10. To displace, and raise or lower the ramp 11, hydraulic, pneumatic,gear, and/or ram mechanisms may be employed. It is noted that thespecific mechanisms to articulate and extend the ramp 11 is not intendedto limit the true scope and spirit of the present disclosure. Of course,a variety of ramp lengths can be employed such as a ramp 11 that canrange between twelve and sixteen feet.

In a non-limiting exemplary embodiment, the two-hundred-poundtelescoping ramp 11 may be extendable from about seven to fourteen feetin longitudinal length. Power-actuated and automated car 36 and rail 35mechanism 21 displaces the ramp 11 along at least a portion andpreferably an entire perimeter of the cargo vehicle 12 is alsoadvantageous. The controller 13 includes a user interface for receivinga plurality of user inputs that instruct various components of thesystem 10 to operate in a desired mode. For example, the controller 13deploys the ramp 11 along the perimeter of the vehicle 12 and to adesired position adjacent to the vehicle 12 loading doors, which may belocated at one or more sides of the vehicle 12. Selective powereddisplacement of the ramp 11 enables loading and unloading of cargorelative to the vehicle 12.

In a non-limiting exemplary embodiment, the ramp 11 is fully automatedby a cable-driven car 36 mechanism or other mechanism (firstdisplacement mechanism) along a guide rail 35, and a telescopicallyactuated ram mechanism extends and retracts the ramp 11 between minimumand maximum longitudinal lengths, respectively.

In a non-limiting exemplary embodiment, winch 38 cables are connected tothe other components. For example, the winch cable 39 is positionedalong the guide rails 35 and attached to the car 36, which has rollers37 wheels that roll along the guide rails 35.

In a non-limiting exemplary embodiment, a ramp 11 ram (thirddisplacement mechanism) is operated by 12-volt linear actuators toextend and retract the longitudinal length of the ramp 11. Suchcomponents simplify the installation and maintenance while also giving amuch cleaner presentation to the consumer. Of course, variousdisplacement mechanisms (e.g., hydraulic pistons, pneumatic pistons,worm gears, pulleys, etc.) may be employed without departing from thetrue spirit and scope of the present disclosure.

Advantageously, while ramp 11 is docked, the cargo vehicle 12 will startand the ramp 11 is connected to a proprietary automatic, shock proof,charging system 10 as shown in the figures. Keypad code entry isrequired to activate the various ramp 11 displacement mechanisms. Thisprovides a child safety feature. The keypad and system 10 deactivate inabout 4.5 min+/−. The access code needs to be reentered every time theramp 11 position is changed. Once activated, the ramp 11 will only moveout of the docking station, all other buttons are inactive. When anybutton is pressed, the lights will flash, and the horn will soundwarning bystanders.

Once the ramp 11 exits the docking station, all buttons begin to work.The automatic, proprietary, charging system 10 disconnects anddeactivates. Now, the cargo vehicle 12 will no longer start. The ramp 11can be traversed around the entire vehicle bed but will automaticallystop prior to reaching the end nearest the driver's door. The ramp 11can be lowered at any position along the vehicle bed. Once the ramp 11begins to lower, it can no longer traverse. It cannot be extended untilit is approximately level with the ground. Once the ramp 11 isapproximately level with the ground, it may be extended to the desiredlength. While on the ground, a second set of lights at the tip of theramp 11 start to flash, warning of a trip hazard. If the customer triesto “ride” the ramp 11 or lift a heavy item, the hydraulic unit willsense it and bypass the system 10. The deployment process should bereversed to return the ramp 11 to its docking station. However, if thecustomer attempts to raise the ramp 11 prior to retracting it, the ramp11 will automatically retract. Once the ramp 11 is fully raised it canbe traversed back to is docking station. The ramp 11 will automaticallystop when docked and reconnect itself to the charging station. Thevehicle will now start.

In a non-limiting exemplary embodiment, the controller 13 may beprogrammed to automatically dock the ramp 11 via a single user input(e.g., single button).

In a non-limiting exemplary embodiment, the ramp deployment system 10further includes a third ramp displacement mechanism 23 configured toselectively adjust a longitudinal length of the ramp 11 along the thirdtravel path 33 while the ramp 11 is disposed at the third position 26(e.g., lengthen/shorten the ramp 11 for uneven ground surfaces such aswhen the ramp 11 is rested on a stairway, street curb, unloading dock,etc.). Such a structural configuration provides the new, useful, andunexpected result of enabling a user to safely and succinctlyextend/retract the ramp 11, as needed, and without exerting undueenergy.

Notably, each of the first ramp displacement mechanism 21, the secondramp displacement mechanism 22, and the third ramp displacementmechanism 23 is operatively coupled to the controller 13 and the powersource 14, such that a user is able to selectively control the movementof the ramp 11 as desired at the cargo transport container 55.

Advantageously, the at least onedrive motor 58 is configured to displace the trolley 36 in a forward andopposed rearward direction along the guide rail 35. Such a structuralconfiguration provides the new, useful, and unexpected result ofenabling a user to safely and succinctly displace the ramp 11 to adesired position along a perimeter of the cargo transport container 55proximate to an access door 98 thereof, (e.g., displace the ramp arounda corner of the guide rail), as needed, and without exerting undueenergy.

In a non-limiting exemplary embodiment, the guide rail 35 includes anupper rail 35 a and a lower rail 35 b each operably coupled to thetrolley 36.

Advantageously, the firstroller assembly 60 and the second roller assembly 65 are independentlypivoted along a first rotation axis 70 and a second rotation axis 71,respectively, while traveling around a corner of the guide rail 35 alongthe first travel path 31 (see FIGS. 31, 97-98). Notably, the firstroller assembly 60 and second roller assembly 65 are registeredorthogonal 99 relative to the fulcrum pivot axis 45 when the trolley 36travels along a linear portion of the guide rail 35. Alternately, thefirst roller assembly 60 and second roller assembly 65 are registered atoblique angles 99 a relative to the fulcrum pivot axis 45 when thetrolley 36 travels along a curvilinear portion (corner) of the guiderail 35.

Such a structural configuration providesthe new, useful, and unexpected result of enabling a user to safely andsuccinctly displace the ramp 11 to a desired position along a perimeterof the cargo transport container 55 proximate to an access door 98thereof, (e.g., displace the ramp around a corner of the guide rail), asneeded, and without exerting undue energy.

In a non-limiting exemplary embodiment, the trolley 36 includes a centerlink bracket 75 intermediately disposed between the first rollerassembly 60 and the second roller assembly 65.
